This article contains an analysis of metaphysics in historical narrative, especially as it pertains to the study of authoritarianism and populism, and a brief exploration of the political implications of metaphysical narratives. The article engages closely with twentieth-century accounts of the origins of authoritarianism and populism and related topics insofar as they are relevant today. Some present-day authors continue to adopt some of the tropes of twentieth-century accounts, though they do so without acknowledging the uncertainties and doubts expressed by twentieth-century historians and social scientists with regard to their own paradigms. The analysis proceeds through an immanent critique, examining the internal contradictions of complex notions. The focus is on teleology and transcendentalism. Teleology occludes short-term causality, contexts, and conjunctures. It entails anachronism, or the retrospective attribution of meaning, and ontological fatalism, which renders historical explanation irrelevant. Eschewing fatalism means allowing for the causal efficiency of intervening conditions, which contradicts the premises of the teleological approach. The reification of stages (or eras) in teleological successions leads to asynchronies, or the coexistence of elements belonging to different totalities. The formulation of origins as predispositions and potentialities entails a transcendental approach. Immanently, there are no potentialities but actual existents immersed in their historical context; these can only be potentialities with respect to a transcendental being or essence. But this approach leads to irresoluble contradictions and an alienated form of history in which human agency and actors themselves are only manifestations of a beyond. The neglect of social antagonisms as immediate causes of authoritarianism entails a specific political position. The postulation of populism as transcendentally equivalent to authoritarianism carries a negative valuation of challenges to liberal democracy. With a less deterministic approach to history, analytical and normative assessments become less predetermined.  相似文献

This paper presents strong and well dated evidence of the presence of Micropogonias furnieri in areas that are currently out of distribution. This evidence comes from hunter–gatherer archaeological sites along the north Patagonian coast (Argentina). Our results allow us to determine a change in the spatial distribution of M. furnieri during the Holocene, which are possibly linked to biogeographic changes in a set of species at regional level. Finally we discuss the potential for archaeological evidence in the service of spatial and biogeographic studies of different species.  相似文献

How is the Cold War understood in an expanding and diversifying historiographical field? Conceptual precision and specificity seem to be giving way to a looser understanding of the Cold War as an era that encompassed different although interconnected conflicts and transformations. Some scholars ask for specificity and consistency while current centrifugal trends point to multiple approaches and centres of interest. Diversity is galvanising the field, but historians need to (re)define their object of inquiry and strive for at least a minimum of conceptual clarity. In particular, we should aim at a broad cultural understanding of the Cold War, contextualise it in larger processes of historical change without confusing the two dimensions, and reassess relations between Europe and other Cold War contexts.  相似文献

The data from excavations around the hospital of Santa Maria in Siena help to build a picture of the city in the early Middle Ages. Comparison is made with the rural site of Montarrenti, and significant differences between the economic development in the town and country are observed, although both suffered decline. Settlement, and economic activity in the city of Siena are seen to go into recession in the post‐Roman period, but signs of growth become visible from the ninth century onwards.  相似文献

At the end of 2018, the first season of excavation was carried out at the shell midden site of UAQ38. The site occupies the top of a sand dune not far from UAQ36 and UAQ2, two other recently investigated Neolithic shell middens. Several well-stratified anthropogenic levels were excavated at UAQ38, which can be dated mainly to the 5th millennium BC, although the recorded artefacts suggest a possible older date for the lowest levels. Food waste, post-holes, fireplaces, and burnt shell dumpings attest to human activities that took place at the site over a rather long period of time. Here the stratigraphic sequence will be presented, together with a first overview of the artefactual assemblage. The collected data will be concisely discussed in order to fit the site within the typology of Neolithic settlements that can be proposed for the area. UAQ38 is so far the only Neolithic site along the northeastern coast of the UAE for which stratified charcoal is available for dating.  相似文献

Several authors agree that stone surface consolidation works should not significantly alter original mechanical and hygrometric properties of the stones in order to avoid differential stress between the consolidated and non-consolidated parts. Specific limitedly destructive methodologies have been developed for assessing the variation in both mechanical and hygrometric properties, but they require preliminary calibration procedures that are very costly to adopt in terms of both time and money. This research study describes an analytical and experimental procedure aimed at obtaining the necessary hygrometric and mechanical characterization of natural and/or artificial stone, before and after consolidation works, by simply assessing the variation in the distribution of the porous structure.  相似文献

Under Jayavarman VII (1182/83-ca.1218 CE) the Khmer empire reached its apex, leaving a heritage of major construction works and unique artistic production. The stone materials of several sculptures produced under his reign were characterized and compared to possible geological sources in northern and eastern Cambodia. The data suggest that a specific type of sandstone, rich in volcanic detritus, was deliberately selected and quarried from a Triassic sedimentary sequence exposed far from Angkor, the main political and economic center at that time.  相似文献

Martinelli, A.G., Bogan, S., Agnolin, F.L., Ribeiro, L.C.B., Cavellani, C.L., Ferraz, M.L.F. & Teixeira, V.P.A., iFirst article. First fossil record of amiid fishes (Halecomorphi, Amiiformes, Amiidae) from the Late Cretaceous of Uberaba, Minas Gerais State, Brazil. Alcheringa, 1–9. ISSN 0311-5518.

The first fossil amiid fishes (Halecomorphi, Amiiformes) from the Late Cretaceous Marília Formation (Bauru Group) at Uberaba County, Triângulo Mineiro region (Minas Gerais State, Brazil), are described. The material includes some partial maxillae, a dermopterotic, a cleithrum, several vertebral centra and teeth. Features such as the absence of a supramaxillary notch on the dorsal edge of the maxilla, a wide and deep pit on the maxilla for the articulation of the premaxilla, anterior portion of the maxilla with a sub-circular cross-section, teeth with acrodine cup with strong mesial and distal keels, among others, permit confident referral of the material to the Subfamily Vidalamiine (Amiidae), previously recognized in Lower Cretaceous strata of northeasthern Brazil. These specimens constitute the first Late Cretaceous record of this group in Brazil and one of the few in South America.
